A Ruin Maniac (Japanese: いせきマニアRuin Maniac) is a type of Pokémon Trainer that first debuted in the Generation III games. They are often depicted as stereotypical explorers, shown in Generation III as old men in safari outfits and pith helmets, generally having the appearance of an archaeologist in the field. In Generation IV they are younger and wear fedoras and jackets, which make them look very similar to Indiana Jones.

They can usually be seen near any archaeological sites containing rare Pokémon or events. One such Trainer in Generation IV proposes a contest between the player and himself to determine which is faster: the player catching 26 Unown, or the Ruin Maniac digging through the Maniac Tunnel.

In the manga

A Ruin Maniac named Nobuo/Dusty is seen battling Hex Maniac Valerie in the Battle Dome. While it is unknown who won, what is known is Dusty at some point lost a match, eliminating him from the tournament.
